HV257 - 32-Channel High Voltage Sample and Hold Amplifier Array

General Description

The Supertex HV257 is a 32-channel, high voltage, sample and hold amplifier array integrated circuit.

It operates on a single high voltage supply, up to 300V, and two low voltage supplies, VDD and VNN.

All 32 sample and hold circuits share a common analog input, VSIG.

Key Features

  • 32 independent high voltage amplifiers.
  • 300V operating voltage.
  • 295V output voltage.
  • 2.2V/µs typical output slew rate.
  • Adjustable output current source limit.
  • Adjustable output current sink limit.
  • Internal closed loop gain of 72V/V.
  • 12MΩ feedback impedance.
  • Layout ideal for die.
